Fedora 8 upgrade breaks automatic CD / DVD detection

After upgrading from Fedora 7 to Fedora 8, CD's and DVD's were no longer detected on insertion into the drive, although they could still be mounted from the command line. I first noticed this issue after upgrading from FC6 to F7.

Apparently what's happened is that a file

/etc/hal/fdi/information/media-check-disable-DVDW_TS_L532M.fdi

is created during the upgrade. The effect of this file is to turn off automatic detection of media insertion. I don't know why this is necessary, but whatever the reason, having to manually mount CDs and DVDs is an inconvenience I'd rather live without.

To fix the problem, I edited the aforementioned file, replacing the line

<merge key="storage.media_check_enabled" type="bool">false</merge>

with

<merge key="storage.media_check_enabled" type="bool">true</merge>

and restarted the hal deamon:

service haldaemon restart

Reclaim your computer!

A personal computer is called a personal computer because it's yours. Anything that runs on that computer, you should have control over.
— Andrew Moss, Microsoft's senior director of technical policy, 2005

The most serious impediment to a lasting archive is the evolution of media, platforms, formats, and the applications that create them. Unique, proprietary, and constantly evolving data formats such as Acrobat-4, MPEG-4, Oracle 8, Quicken 2001, Real G2, and Word 2000 suggest or even guarantee obsolescence.
